The instrument is helpful when a diagnosis of ADHD is being considered.The test is taken at a computer for children age 6 and older. The participant presses the space bar or clicks the mouse button when a letter other than X shows up onscreen. Letters appear on the screen with different time intervals between each one. Exactly 14 minutes is required for completion not including instruction and a practice test. This test shows strong validity.
